To tack on: because Ethernet is a "dumb" technology, meaning each device must receive, already have, or initiate it's identification, the complexity required on each component connected would have to increase.
At the same time, with serial technology becoming more homogenous, (like SAS / SATA) I can see that as an internal platform. Already, there are boxes with all SATA.. SATA HDDs, SATA DVD Writers, etc. -----Original message----- From: "Greg Sevart" [EMAIL PROTECTED] Date: Wed, 30 Mar 2005 11:49:23 -0600 To: "The Hardware List" [email protected] Subject: Re: [H] Idea regarding internal system interconnects. > Just a little bit more... :) > > SATA is already 150MB/s, with the 300MB/s SATAII already growing in > popularity.
